A budget is very important. Without that, we don't know what to recommend. If it's truly power you are after and can fork over 2 grand, the Krell 400xi may be the way to go. If you're trying to do it for under a grand, the musical fidelity A300 has about 150 watts per channel. In the middle, I would take Classe CAP 151 for about 1200-1400 on the used market.
If you're able to go over 2K, the Musical Fidelity KW500 might be all you need. 4500-4700 is a reasaonable going rate for these 500 wpc monsters.
